If bright colored fringes and outline highlights are cluttering your view while shooting, you can disable focus peaking. I’ll show you how to turn off focus assist in the Blackmagic Camera app.
1. Open Blackmagic Camera App

Launch the **Blackmagic Camera** app on your iPhone.
2. Open Monitoring Settings

Tap the **Monitor** button on the control bar.
3. Locate Focus Assist

Tap the **Focus Assist** icon (marked with peaking lines).
4. Toggle Off to Clear Viewfinder

Tap the icon again so it turns off and the colored edge outlines disappear completely.
